Adding _LRG image to the bottom of each product listing

Hi Guys,

I would be really keen on adding the LRG image of every product automatically at the bottom of each product listing. I really dont know how to code this in to do it automatically.

I could of course just use html in every single product listing but that would be doing things the hard way to say the least. Here is my stylesheet for the product info/listing...

centerColumn {
margin: 0 auto;
padding: 0;
width: 690px;
}
#productWrapperBox {
margin:0;
padding:0;
width:100%;
/border:1px solid #000;/
}

#productImageBox {
margin:0;
padding:0;
float:left;
width:34%/250px/;
}
#productMainBox {
margin:0;
padding:0;
float:right;
width:66%/440px/;
}
#productPrices {
line-height: normal;
padding: 0.8em;
text-align: center;
font-size: 2em;

}
#productAttributeBox {
margin:0;
padding:0;
float:left;
width:48%;
}
.optionName {
margin: 0 0 0.2em 0.5em;
line-height: normal;
font-size: 1.1em
}
#productBuyBox {
margin:0;
padding:0 ;
float:right;
width:48%;
}
#cartAdd {
margin: .2em;
padding: 0 .2em;
/float: right;/
text-align: center;
border: 1px solid #000000;
}
.wishlist {
margin: .2em .5em;
padding: 0 .2em;
float: right;
text-align: center;
}
#cartAdd ul li {
list-style: none;
}
#productDescriptionBox {
margin:0;
padding:.2em 0;
clear:both;
float:left;
width:100%;

In addition to this I would really like the image to be centered but something in the above code or on the main stylesheet makes everything only line up with the text colum and not the center column.

I dont suppose someone could point me to a good article or help me out a little. Been at this for a few hours now trying to work it out and I could do with actually making progress today!
